A more thorough explanation:

Definition: Overreaching is when someone takes unfair advantage of another person, often through fraudulent means. It can also refer to when someone goes too far and ends up defeating their own purpose.

Example 1: A salesman convinces an elderly woman to buy a product she doesn't need by lying about its benefits. This is an example of overreaching through fraudulent means.

Example 2: A politician promises to lower taxes to gain votes, but ends up raising taxes instead. This is an example of overreaching by going too far and defeating their own purpose.

These examples illustrate how overreaching can occur in different contexts, but ultimately involves taking advantage of someone or going beyond what is reasonable or achievable.
